Need something to digitally record your hand-drawn notes but have no use — or no money — for the iPad's do-everything awesomeness? Meet the NoteSlate ($100). This simple device sports a one-color eInk display in either white, black, green, blue, or red, a smooth, simple design, a battery good for 180 hours of work, and a simple list of inputs including a special pen with eraser, a mini-USB port, an SD card slot, and a 3.5mm headphone jack for listening to MP3s — okay, so they snuck that last unnecessary feature in, but what doesn't play MP3s these days?
